- Drive development of process and materials for proprietary photomask fabrication. - Conduct material and surface analysis to verify mechanical and optical performance. - Characterize design performance to verify engineering requirements are met. - Optimize material sets.
Our goal is to develop a cost effective route to fabricate large area, transparent metal mesh electrodes (NanoWeb™) on rigid and flexible substrates; and nanostructured-based antireflective glass for displays, architectural windows and automotive parts. In this context, my team and I, - Elaborate and develop soft masks for continuous seamless patterning with features width ranging between 100 to 300 nm. - Demonstrate large area conical nanostructured glass with reflectivity below 0.1%. - Develop processes for lift-off resulting in metal mesh on glass and flexible substrates. - Achieve sheet resistances between 2 to 5 Ω/☐ on flexible (PET) and rigid (glass) substrates, while keeping the transparency over 95%.
- Design and set up Chabal’s research chemistry lab at University of Texas at Dallas. - Develop Successful platforms for controlled deposition/attachment/dispersion of densely packed quantum dots monolayer, and investigation of energy transfer on flat/high aspect ratio (nanopillars) surfaces for future photovoltaic applications. - Achieve control of deposition of metallic contacts on organic monolayers using atomic layer deposition (ALD) for molecular electronic applications. - Elucidate the mechanism of etching and reactivity of SiC-SiO2 and SiC-N-SiO2. - Grow robust and high quality organic monolayers, containing different reactive head groups, directly attached to silicon surfaces for sensor application or nanoparticle attachment. - Improve biosensor platforms by increasing their stability and reliability, compare the detection limits between nanowires and nanoribbons sensors, and successfully adapt the bio-sensing chemistry to be compatible with devices fabrication. Project funded by Texas Instrument.
- Developed, improved and characterized high quality organic monolayers directly bonded to silicon. - Uncovered the electrical properties and transport mechanisms using experimental and theoretical analysis. - Modified these layers via X-ray or UV irradiation to demonstrate first case of organic monolayer doping.
